BRUSH-WIPER.

SEEGFICATION forming part of Letters Patent No. 541,224, dated June 18,1895. f

Application tiled January 18, 1895. Serial No. 535,350. (No model.)

To all whom -zit may concern.:

Be it known that I, FREDERIC L. CLARKE, a citizen of the United States,residing at Glens Falls, county of'Warren, and State of New York, haveinvented certain new and useful Improvements in Brush-lVipers,V of whichthe following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the letters ofreference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a central vertical section of amucilage-bottle, showing a brush, partly in section and partly inelevation, supported by the handled cover, and the brush-wipermechanism, shown in vertical section, taken on the broken line l 1 inFig. 2. Fig. 2 is a bottom plan View of the wiper mechanism detached.Fig. 3 is a vertical section of the wiper mechanism, taken on the brokenline 3 3 in Fig. 2. Fig. 4 is a side elevation of one of thewiper-plates. Fig. 5 isa plan view of the partly-formed wiper-frame.

A represents a mucilage bottle; A-, a brush; A2-, a cover for the bottleand asupport for the brush, and A3- a handle for the cover and brush,all made in the usual well known manner.

The brush-wiper mechanism comprises a supporting frame 13.- which may beof sheetmetal, out and swaged by suitable dies to form the annulardepending peripheral flange B- adapted to inclose the top of the bottleand secure the frame thereon.

The peripheral depending ange may be integral with the frame or aseparate ring soldered or otherwise secured to the frame body.

The frame-bodyhas the general form of a disk, the middle portion beingcut away, as shown in Fig. 5, to form a rectangular opening B2- and theslits B3 and B4 projected from the middle opening toward the peripheraledge of the disk and terminating at points in the lines of anotherrectangular gure represented by the dotted lines B5- and BG- in Fig. 5,the lines B4- being approximately radial to the disk and extending tothe corners of the dotted rectangular figure.

By bending at the dotted lines B--and B6- the four triangular portionsB7- of the disk,

formed by the slits, down approximately at right angles to the plane ofthe disk, as shown in Figs. l and 3, I form the hangers for thewiper-plates C- and C-.each of which is provided at'each end at or nearits upper edge, with a trunnion C2 adapted to enter and have its bearingin the aperture B8- formed in the adjacent triangular hanger 137-.

The lower edges of the wiper-plates are parallel with each other andoscillatory to and from each other. The oscillatory movement of eachwiper-plate is controlled by a spring S- one end of which is secured tothe diskbody or frame as by solder S- and the other end SL- bears uponthe wiper-plate. The springs tend to force the lower edges of thewiper-plates into engagement with the brush inserted between them asshown in Fig. l.

When the brush is withdrawn, the normal position of the lower edges ofthe wiper-plates is in engagement with each other, as shown in Fig. 2.As a means for maintaining such normal position in the middle verticalplane of the apparatus and midway offthe 'vertical planes cutting thetrunnion-bearings of the respective wiper-plates, I bend along thedotted lines B5 the rectangular shaped parts B9- down to the positionshown in Fig. 3, to form stops for the wiper-plates, to limit theiroscillating movements toward each other, whereby they are each preventedfrom passing the middle vertical plane. The parts B10- may also each beslightly bent along the dotted lines B6- to incline downwardly andoverhang the upper edges of the wiper-plates, whereby any drippings fromthe brush, as it is withdrawn from the wiper-plates, are prevented fromcoming in contact with the springs to impair their action.

The operation of the apparatus is as follows: The brush is inserted inthe bottle by pushing it down between the yielding wiper-plates whichare forced apart as shown in Fig. 1. After the brush has filled withmucilage or other contents of the bottle,.it is withdrawn,

IOO

and the wiper-plates being forced by the springs against the brush attheir lower edges, Wipe off the superiiuous mucilage adhering to theouter surface of the brush, and permit it to drop back into the supplybeneath.

The .tension of the springs can be varied for varying uses, whereby moreorlessof the fluid deposit on the brush can be'removed as desired.

My improved apparatus is adapted for use with paint brushes, whitewashbrushes or other brushes supplied by dipping, and can be applied tobottles, cans, pails or other Huid receptacles.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a brush-wiper, the combination with a supporting frame, and meansfor sustaining the frame upon the mouth of a fluid receptacle, of a pairof movable spring-actuated wiper-plates, and a stop for limiting themovement of the plates, substantially as described.

2. In a brush-wiper, the combination with a supporting frame, and meansfor sustaining the frame upon the mouth of a Huid re- 25 v ceptacle,of apair of movable spring-actuated wiper-plates, and anoverhangingguard-plate above each wiperplate, for protectiugitsactuating spring, substantially as described.

3. In a brush-wiper, the combination with 3o l a pair of oscillatory,downwardly-converging spring-actuated wiper-plates, of aplate-supporting frame formed from an integral plate of sheet-metal withdepending hangers containy ing bearings for the Wiper-plates, and a stopfor 3 5 FREDERIC L.
